SAM G. GIVENS, 0F PAIDUCAH, KENTUCKY, AND HENRY LE'WIS, OF NEW LIBERTY, ILLINOIS.

STOVEPIPE DAMPER AND CLEANER.

Application filed May 17, 1915.

To all whom it may concern:

Be it known that we, SAM G. GIvENs and HENRY LEWIS, citizens of the United States, and residing at Paducah and New Liberty, respectively, in the counties of McCracken and Pope and States of Kentucky and Illinois, have invented certain new and useful Improvements in Stovepipe Dampers and Cleaners, of which the following is a specification.

Our invention relates to improvements in Stovepipe dampers and cleaners, disclosed but not claimed in our patent of May 19, 1914, No. 1,097,423.

The object of our invention is the provision of simple, durable and inexpensive means which will perform the function of a damper and which can be instantly operated to effectively clean the entire stove pipe wlth elbow portion.

With this object in view our invention consists of a Stovepipe damper and elbow embodying novel features of construction and combination of parts substantially as shown, described and claimed.

Figure 1 is a vertical longitudinal sectional view of a stove pipe equipped with our combined damper and cleaner. Fig. 2 is an enlarged detail View of the head and spring connection of our device. Fig. 3 is a vertical sectional view of the elbow and ends of the vertical and horizontal pipes, showing the position of the damper and cleaner when used to clean. the vertical pipe, and Fig. 4, is a perspective view of the stove pipe with our invention applied.

Referring by numeral to the drawings in which similar numerals denote corresponding parts in all of the figures, the numeral 1 designates the flue, 2 the fastening sleeve; 3 the horizontal stove pipe section having outlet e to flue; 5 the elbow; and 6 the vertical pipe section. The elbow is formed with the bulged or raised portion 7, formed with a longitudinal slot 8, at each side of which are arranged cleats 9, forming guides for the curved plate 10. The curved plate 10, it is thus seen is movable back and forth in the guides but always serves as a closure for the slot 8, and is provided with an opening 11. Fitting and movable in said opening 11, is the rod 12, having a handle 13 on its ex- Specification of Letters Patent.

posed end with its other portion and end passing through the plate 10 into the stove pipe the rod thus being allowed entrance into either the horizontal or vertical section of the stove pipe. The inner end 12, of the rod is reduced and has secured thereto by a suitable fastening 14, one end of the coiled spring 15, whose other end is secured by a fastening 16, to the pin 17, passing through an opening 18 in the cleaner head, and having a head 19, to retain the pin in the said cleaner head.

The cleaner head is of novel and peculiar construction and consists of a pair of concaved or curved disks 20, separated by an asbestos sheet 21, the disks snugly fitting in the stove pipe to efiect a proper cleaning and the asbestos acting as a non-conductor of heat to prevent the disks from wear by the action of the heat.

The spring between the operating rod and head is very sensitive and allows the cleaner head to always assume the proper position when cleaning the pipe. In acting as a damper the head may be placed in the elbow or either section of the pipe to entirely or only partially close the pipe. Disks may be made of woven wire when not desired to be used as damper.

It will be understood that the sliding curved plate 10, allows the rod to be moved to place the head inthe elbow or the horizontal or vertical section and permit the movement of the head therein to act as a damper or to effect a rapid and thorough cleaning of the stove pipe.

lVe claim:

1. In combination with the stove pipe and connecting elbow provided with an elongated slot, guides at the side of said slot, a plate closing said slot and movably mounted in said guides, a rod passing through said plate and having one end in the pipe and the other end outside said pipe, a spring having one end secured to the end of said rod in the pipe and a cleaner head secured to the other end of the spring.

2. In combination with the stove pipe and connecting elbow provided with an elongated slot, guides at the side of said slot a plate closing said slot and movably mounted in said guides, a rod passing through said plate and having one end in the pipe In testimony whereof We aflix our signaand the other end outside sald pipe, a spring tures in presence of tWo Witnesses. having one side secured to the end of said rod in the pipe and a cleaner head secured SAM Gr. GIVENS. to the other end of the spring, said cleaner HENRY LEWIS.
